I'm saying I'd like to find out what, if any, parts out there I'd have a choice on swapping out, from barrels to stocks... I've got another 870 in 20ga, and I know between that and the 12ga, you can configure the gun in any myriad of ways. (cantilever scoped rifled, rifled slug w/iron sights, pistol grip stock, etc. etc.) But I can't seem to find much anywhere for the 16ga. I don't know if the 16 will accept anything from the 12 to swap things like stocks. I also don't know if anyone knows of some shop or store that specializes in 870's. My 1100's for birds and clays. My 11-87 is Special Purpose for Turkey. My 870 in 20 is for deer, and then I've got this ol' Wingmaster. Mostly just for fun, (and if I ever go pheasant again) but I'd just like to know if I've got any "options" for it. I like options with my firearms.
